WebIntroduction. Determining if there are Critical Control Points (CCPs) in your process and establishing critical limits for these CCPs are essential steps in the development of a Preventive Control Plan (PCP) that will effectively control hazards significant for your food.

Often there is more to the analytical method than just performing a reaction or submitting the analyte to direct analysis. Many analytical methods developed in the laboratory, especially these involving the use of a delicate scientific instrument, require a sample preparation, or a pretreatment of the samples prior to being analysed. For example, it might be necessary to heat a sample that is to be analyzed for a particular metal with the addition of acid first (digestion proce… Web2 de abr. de 2004 · The maximum contaminant level goal (MCLG) is non-enforceable level at which no known or anticipated adverse effects on the health of persons occur and which allows adequate margin of safety.
